Bill Johnson discusses his latest passion project for HOK, designing and building the Mercedes-Benz Stadium in Atlanta, housing both the NFL Falcons & Atlanta United FC. Johnson talks about the preparations, including ownership's desires to build stadia that reflects a European taste. Johnson also shares some of the aspects in dealing with shared facilities, including the NY Giants/NY Jets venue project, MetLife Stadium. Twitter: Johnson993_bill
